Putting fish safe silicone over not-fish-safe Silicone?

[FishFreak95]

Is it OK to put a fish safe silicone over a silicone that's not really safe for fish? I made a shotty aquarium out of a 30(i think) gallon bucket and cut a square hole in the side with a piece of acrylic I molded to fit. I have siliconed it in place and it is water tight but the silicone is colored and has some anti-mildew additives so I need to put aquarium silicone over it to make it safe.

Silicone does not stick very well to silicone. So the answer is no.

Dow 795 sticks very well to other silicone so i say yes as long as you get some 795.

First lol, if it holds for a week, ill test it on some feeder guppies. If it all works out ill add some small ca cichlids, maybe panama cichlid or ellioti

I personally used fish-safe silicone, however, I was recently told from a guy who builds tanks for a living that as long as your silicone is not a mold/mildew silicone, then it doesn't matter. But as I said I went on the safe side!
